在“描绘小灯泡的伏安特性曲线”的实验中,利用实验得到了8组数据,在图中所示的I-U坐标系中,通过描点连线得到了小灯泡的伏安特性曲线。

①根据图线的坐标数值,请在图中选出该实验正确的实验电路图    (选填“甲”或“乙”)。

②根据所选电路图,请在图中用笔画线代替导线,把实验仪器连接成完整的实验电路。

③由伏安特性曲线,该小灯泡的电阻随电压的升高而    。(选填“增大”、“减小”或“不变”)

④根据伏安特性曲线,可判断出图中正确的关系图像是(图中P为小灯泡功率,I为通过小灯泡的电流)(  )

⑤将同种规格的两个这样的小灯泡并联后再与R=10Ω的定值电阻串联,接在电动势为8V、内阻不计的电源上,如图所示。闭合开关S后,则电流表的示数为         A,两个小灯泡的总功率为        W。
